Abstract

Portable device ( 1 ) for analysing pH or another variable by electrochemical measurement comprising a sensor ( 2 ), a microprocessor ( 3 ) and display means ( 4 ) for the results of the analysis. The portable device makes it possible to carry out pre-diagnoses quickly and easily without the need for specialist staff.

Claims

exact text as granted — not AI-modified
1 - 20 . (canceled) 
     
     
         21 . A method for self-diagnosis of lithiasis in a subject in need thereof comprising:
 (i) contacting a urine sample obtained from said subject with a portable device comprising an electrochemical sensor; and,   (ii) measuring pH and/or ionic calcium in said urine sample using the electrochemical sensor in said portable device, thereby providing a measurement value of pH and/or ionic calcium;   wherein a measurement of pH and/or ionic calcium above or below at least one threshold value is indicative of lithiasis or risk of lithiasis.   
     
     
         22 . The method according to  claim 21 , wherein the electrochemical sensor is mounted on a lid affixable to a specimen collection cup. 
     
     
         23 . The method according to  claim 21 , wherein the electrochemical sensor comprises a pH sensor, a calcium sensor, or a combination thereof. 
     
     
         24 . The method according to  claim 21 , wherein the electrochemical sensor further comprises a redox potential sensor, and the variable indicative of lithiasis or risk of lithiasis further comprises redox potential. 
     
     
         25 . The method according to  claim 21 , wherein the lithiasis is uric acid lithiasis, hydroxyapatite lithiasis, oxalocalcium lithiasis, or a combination thereof. 
     
     
         26 . The method according to  claim 21 , wherein the method comprises one threshold value. 
     
     
         27 . The method according to  claim 21 , wherein the method comprises two threshold values. 
     
     
         28 . The method according to  claim 27 , wherein the two threshold values correspond to pH. 
     
     
         29 . The method according to  claim 27 , wherein one threshold value corresponds to pH and an one threshold value corresponds to ionic calcium. 
     
     
         30 . The method according to  claim 28 , wherein the first threshold value is indicative of nucleation and formation of uric acid crystals. 
     
     
         31 . The method according to  claim 28 , wherein the second threshold value is indicative of capacity of nucleation and growth of hydroxyapatite crystals. 
     
     
         32 . The method according to  claim 30 , wherein the first threshold value is pH 5.5 and a measurement value lower than said threshold value is indicative of lithiasis or risk of lithiasis, and wherein said lithiasis is uric acid lithiasis. 
     
     
         33 . The method according to  claim 33 , wherein the second threshold value is pH 6 and a measurement value higher than said threshold value is indicative of lithiasis or risk of lithiasis, and wherein said lithiasis is hydroxyapatite lithiasis. 
     
     
         34 . The method according to  claim 21 , wherein the subject is a human subject.
